After months ofcareful efforts to set up the telescope to work at the best possibletechnical level, those involved in the project are looking withsatisfaction at the fruit of their labour: APEX is not only fullyoperational, it has already provided important scientific results.
"Thesuperb sensitivity of our detectors together with the excellence of thesite allow fantastic observations that would not be possible with anyother telescope in the world," said Karl Menten, Director of the groupfor Millimeter and Sub-Millimeter Astronomy at the Max-Planck-Institutefor Radio Astronomy (MPIfR) and Principal Investigator of the APEXproject.
Millimetre and sub-millimetre astronomy opens excitingnew possibility in the study of the first galaxies to have formed inthe Universe and of the formation processes of stars and planets. Inparticular, APEX allows astronomers to study the chemistry and physicalconditions of molecular clouds, that is, dense regions of gas and dustin which new stars are forming. Among the first studies made with APEX,astronomers took a first glimpse deep into cradles of massive stars,observing for example the molecular cloud G327 and measuringsignificant emission in carbon monoxide and complex organic molecules(see ESO PR Photo 30/05).
The official inauguration of the APEX telescope will start in San Pedro de Atacama on September, 25th.
TheAmbassadors in Chile of some of ESO's member states, the Intendente ofthe Chilean Region II, the Mayor of San Pedro, the Executive Directorof the Chilean Science Agency (CONICYT), the Presidents of theCommunities of Sequitor and Toconao, as well as representatives of theMinistry of Foreign Affairs and Universities in Chile, will join ESO'sDirector General, Dr. Catherine Cesarsky, the Chairman of the APEXBoard and MPIfR director, Prof. Karl Menten, and the Director of theOnsala Space Observatory, Prof. Roy Booth, in a celebration that willbe held in San Pedro de Atacama.
The next day, the delegationwill visit the APEX base camp in Sequitor, near San Pedro, from wherethe telescope is operated, as well as the APEX site on the 5100m highLlano de Chajnantor.
